DRIVING CYCLE FOR PASSENGER CARS ON URBAN ROADS IN PRISTINA, KOSOVO

Abstract

The driving cycle is a significant input for the micro-scale analysis of vehicle emission. Several cities around the world have developed driving cycles based on their driving behaviours, while Pristina still has a lack of studies on this issue. Thus, the first objective of this study was to represent the proper driver behaviour of passenger cars in Pristina by obtaining a driving cycle from real-time measurements on the road. The driving cycle was developed by extracting the micro-trips from 53 491 s of data using a “3-sequential points” algorithm, where 780 micro-trips were detected. Using the K-means method from 780 micro-trips, we selected only 25 to develop the final driving cycle. The second objective was to analyse the effects of different intersections on the final driving cycle parameters. We found that the final driving cycle had significant differences from driving cycle of other cities. Driving habits in Pristina are more aggressive compared to other European cities. Also, we found that the average speed of roundabouts and un-signalized intersections was statistically different from signalized intersections.
